> given CASSANDRA-1155, we should query multiple nodes for the rows
> corresponding to the given index criteria, such that we have a 90% chance of
> getting enough rows w/o having to do another query (but, if our estimate is
> incorrect, we do need to loop and do a 2nd query).
> we start with the first node in token order, so that we only have to query a
> single node for low cardinality (i.e., every index value has many rows
> associated with it). we do this by ordering the keys in the index row, in
> partitioner order.
